Application filed September 3, 1927. Serial No. 217,391.

This invention relates to a certain new and useful improvement in cartons and has for its object the provision, as a new article of manufacture, of a carton having, in addition to its usual opening or open side, a supplemental or, auxiliary top or corner opening and readily manipulated, independent closure means therefor, whereby removal or inspection of the contents of the carton is conveniently facilitated.

And with the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and pointed out in the claims.

In the accompanying drawing,

Figure 1 is a perspective view of a carton embodying my invention; a

Figure 2 is a longitudinal sectional view of the carton; and

Figure 3 is a plan view of the cut and scored blank of which the finished or coinplete vcarton is constructed.

Referring now more in detail and by reference characters to the drawing, which.

illustrates a preferred embodiment of my invention, A designates the finished or complete carton, which is constructed of the blank B shown in Figure 3.

The blank B is composed preferably of card-board or other suitable material of suitable weight, thickness, and dimensions for the desired use and purpose, the carton A being preferably of general flat rectangular configuration and contour, as best seen in Figure 1', with one corner, as at C, thereof, however, obliquely disposed to the opposite and remaining corners of the carton.

For the folding formation of carton A, the blank B is scored transversely along the lines 1, 2, 3, and 4, and thereby divided into an end-wall member a,"a side wall portion I), an opposite end wall portion 0, an opposite side wall portion cl, and a complementing end-wall member c. It will be noted that such score-lines l, 2, 3, and 4 are so spaced that the resulting wall-forming portions a and c are of the'same width or breadth, as

are also the wall-forming portions b and d.

At one side edge and throughout the length of side wall portion d, the blank B is scored longitudinally "along the line 5 and extended laterally for the provision of a bottom-wall forming flap 7", which, in turn, is scored longitudinally along the line 6 in the production of a lip 9. On the same side edge and throughout the length of the end-wall portions a and 0, the blank B is scored, as at 7, 7 and extended laterally for the provision of complementing bottom wall flaps h, h.

,At its end opposite the flap h, the endwall portion 0 is extended, as at 9', and for a suitable distance inwardly from the adjacent side edge of the blank B, the blank is kerfed, as at 8, 8, along the score-lines 2 and 3, the end-wall portion a being then scored on a line, as at 9, running at the base of the kerfs 8, 8, longitudinally of. the blank. The one end-wall portion '0 is thereby reduced in length relatively to the other end-wall forming-portions a, e, and its extension y' converted into a foldable flap, for purposes shortly appearing, which, in turn, is scored, as at 10, and thereb. provided with alip is. Then on opposed o lique lines 11, 11', runningor extending from the base of the kerfs 8, 8, to the adjacent side edge of the blank B, the blank is scored and thereby provided with opposed and oppositely foldable corner flaps Z, Z.

On the same side edge of blank B and 1 provision of a flap m, which, also in turn,

is .scored longitudinally along the line 13 in the production of a lip n. By reason of the corner-flap Z, it will be noted that the one lipped flap m is of reduced width relatively to both its adjacent wall-portion b and the opposite lipped flap 7.

On the same side edge of blank B with the flaps j and m and opposite the flap h, the blank B at its said end-wall forming portion a is scored, as at 14, and extended liaterally for the provision of an additional is so formed and scored, the blank B is readily folded into finished carton shape, the one flap e being brought over and disposed flatwise upon the inner face of, and then adhesively or otherwise fixed to, the

opposite fiap a. With the flaps a and e so the score lines 7 and 7, respectively, when ently the flap f is folded thereover and its lip g tucked in between the side wall I) and the adjacent side ed es of the folded flaps h and o. The so folde and secured flaps h, h, and f thus form a bottom wall, or as termed in some of the appended claims an opposed top wall, of the carton. In a similar manner, the end wall flap 0 and side wall flap m with its lip n are folded relatively to the body of the carton or blank and in a like manner form and provide the first top wall of the carton.

By foldable disengagement of either or both the main or first top flap m and the opposed flap f, the contents of the cartonare readily accessible for inspection or removal.

However, the reduced first top wall flap m and the reduced first end-wall a provide or form in the finished or complete carton a corner-opening continuous with the top opening of the carton, the latter being closable by the independently foldable flap m, and with flap m in carton-closing position, both inspection and often the removal of the carton-contents is readily and conveniently facilitated by the also independfoldable lipped corner-flap j. In closing the carton at its said oblique corneropening, the angular side wall flaps Z and l are first folded inwardly in opposed relation, and the flap j then disposed thereupon and its lip 70, in removable flap-securing arrangement, tucked in beneath the closed top flap m. On reverse folding of the flaps j and Z and Z, a convenient opening into the carton for inspection or removal of its contents is presented and afforded.

The carton, which is simple and inexpensive in structure, thus lends itself to efficient use in many industries.

I am aware that changes in the form, construction, arrangement, and combination of the several parts of my new carton may be made and substituted forthose herein shown and described without departing from the nature and spirit of myinvention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
